No. 20: Nate Diaz

In Nate Diaz's last fight, he was able to do something that no fighter before him had done—finish Jim Miller.

Miller has lost four times in his career to Frankie Edgar, Gray Maynard, Benson Henderson and Diaz. Diaz was the only one to finish him.

With three straight wins since returning to the lightweight division, Diaz earned the right to wait for the lightweight title fight at UFC 150 and will now face Henderson for the lightweight title at UFC on Fox 5.

No. 18: Chael Sonnen

Chael Sonnen came into the fight at UFC 148 with everything to prove. He had a chance to dethrone the greatest fighter of all-time and back up all of his trash talk.

For the first five minutes, he did just that, as he took down and controlled Anderson Silva. Then, in the second round, Silva did what he does best, as he used his pinpoint striking to finish Sonnen by TKO.

Sonnen is currently coaching on The Ultimate Fighter against Jon Jones, and the two will fight in April of 2013 for the light heavyweight title.
